my girlfriend and i bought a townhouse together 8 months ago. by the front door i have a 125g fw predator tank, 95g reef in living room, and 55g cichlid in bedroom. we had 2 friends move in to help pay mortgage. so last week we went out of town for a week on vacation. the only person at the house was the roommate thats my girlfriends friend whom i dont like already. i made everything as simple as possible. individual zip lock bags with day of food marked on them was the only thing for the fw tanks. only think different for reef was remove bubbles from overflow and add top off. after a 7 hour drive home i walk in my front door to a very stinky house and my 125g with black sand in the bottom was full of swollen fish pellets!!!!! the whole bag!!!!! before i could unpack i had to do a 50% water change. and she managed to overflow the refugium under my reef tank! when asked about the food she said she has no idea what happened. im using her next months rent to put a security camera over my tank and the front door!!!
